Prerequisites

Students considering registering for this
course would normally be expected to have completed an intermediate course in
materials science and an introductory course in mechanics of materials, e.g.
MECH2011 and MECH1006.

Course Aims

The course aims to impart a knowledge of all
current Non-destructive Evaluation (NDE) techniques used by industry for defect
and material characterisation. The coverage starts with basic physical
concepts, moving on to systems and practices and ends with current research
challenges. A second part of the course
covers Fracture Mechanics concepts for safe life prediction for engineering
materials and the concept of reliability for safety critical components.

Method of Instruction

Lecture presentations, tutorial classes and two
laboratory classes.

Assessment

The course has the following assessment components:

Written Examination
(3 hours, 75%)

Two Laboratory Reports
(25% overall) written on work undertaken during two lab sessions (QT1) and (QT2)

Review
of a range of non-destructive testing techniques and their advantages and
limitations, including radiography, ultrasonics, magnetic particle
inspection, and alternating current field measurement. The
concept of probability of detection of a crack. Introduction to fracture mechanics. Measurement of material properties in
the presence of a crack. Calculation of failure loads and fatigue crack
growth lives. Application to design and failure analysis.
